Title: Improvements in the manufacture of polymerisation products of 2-chloro-butadiene-1.3.
IPC: C08F36/16
Filed: 1936-01-31
Abstract: In the process described in the parent Specification for the manufacture of soluble vulcanizable polymers of 2-chlor-butadiene-1.3 by emulsion polymerization in the presence of neutral alkali or ammonium salts which exert no oxidizing action under the conditions of working and have no emulsifying action, the yield is increased by working also in the presence of organic solvents which are insoluble in water but dissolve the chlor-butadiene and the polymers.  Suitable solvents are chlorinated aliphatic hydrocarbons such as carbon tetrachloride, benzene, toluene, and carbon disulphide.  These may be added before or during the reaction but before the emulsion separates. In examples, polymerization is effected in emulsion in sodium oleate with addition of ammonium sulphate.  Carbon tetrachloride or xylene is added during the course of the reaction, or benzene prior to polymerization.  The latex formed may be stabilized and the solvent distilled.  Specification 387,340 is referred to.

IPC: G01S5/10
Filed: 1968-01-19
Abstract: 1,248,221. Radio navigation. STANDARD TELEPHONES & CABLES Ltd. 16 Jan., 1969 [19 Jan., 1968], No. 3065/68. Heading H4D. In a collision warning system each craft generates signals representative of its position x, y from a known land-based hyperbolic radio system (e.g. an Omega system), and of its velocity x, y, and broadcasts those signals. At a receiving craft a computer issues an alarm when (x 1  - x 2 )/(#x 1 - #x 2 ) = (y 1  - y 2 )/(#y 1  - #Y2) where the subscripts 1 and 2 refer to another craft and the receiving craft respectively. The transmitted signals may be coded digitally; this is stated to avoid distortion by Doppler effects. Height data may be utilized in addition. Each aircraft can transmit its data in an allotted time slot, using a circuit synchronized with the reception of the Omega system signals. The aircraft transmission may be monitored at traffic control centres.

Filed: 1945-02-08
Abstract: 588,284. Cooling systems for engines. LINDE AIR PRODUCTS CO. Feb. 8, 1945, No. 3178. Convention date, Nov. 11, 1943. [Class 64 (iii)] A liquid cooling circuit for an internal-combustion engine 10 comprising a radiator 14 and a pump 18, has a static reservoir 30 connected by the pipe 54 to a point of low pressure (e.g., a venturi 22 as shown) in the primary circuit. To maintain the temperature of the reservoir 30 above that of the liquid in the venturi, an expansion tank 28 through which is a partial flow of coolant from the engine 10, encloses the reservoir 30. In this way cavitation at the pump entrance is avoided. There is no liquid flow through the tank 30, the pressure inside which is controlled by an adjustable valve 52. The expansion tank 28 serves to de-aerate the coolant and pass it via pipe 32 to the static reservoir 30. The low pressure point may be pitot or orifice, or the pipe 54 may be joined directly to the pump 18. The static reservoir 30 may be heated by exhaust gases or an electric heater if desired.

Title: Method of hardening manganese steel
IPC: C21D7/04
Filed: 1955-02-03
Abstract: 765,305. Altering physical structure. MACLEOD, N. A. Feb. 3, 1955, No. 3194/55. Class 83 (4). A method of hardening an article of austenitic manganese steel comprises placing against the surface of the article to be hardened a sheet of explosive material, exploding said explosive material such that at least a portion of the shock-wave thereby produced will enter said surface and effect hardening of said steel in substantial depth, said hardening diminishing progressively from said surface inwardly the quantity of said explosive material being sufficient to harden said steel in substantial depth without permanently deforming the surface contour of the article. In an embodiment a layer 5 of explosive material, e.g. pentaerythritol tetranitrate, is placed on the upper surface 4 of a manganese steel workpiece 3 and exploded by a detonator 6. A hardness of about 400 Brinell is imparted to the surface 4, said hardness gradually reducing inwardly the normal heat treat hardness of 200 Brinell being encountered about one inch below the surface. The point of a digger tooth 10 (Fig. 2) is hardened by exploding a layer 12 of explosive material shaped to the contour of the point. One detonator is attached to a tongue 13 projecting from the material. After the explosion of the layer 12 another layer may be placed on the point decreasing in thickness from the edge 11 to give an additional hardening to said edge. Fig. 3 shows an explosive layer 15 moulded to the working surface of a manganese steel bowl 14 for a rock crusher and Fig. 4 an explosive sheet 18 applied to the surface of a roll shell 17 for a rolling mill. In the latter embodiment both the explosive and the roll shell are submerged in water or other liquid; sand or metal particles 19 to restrain the explosive force. An electrically ignited detonator 22 is attached to a tab 21. In a still further embodiment a manganese steel article 26 is supported on a layer of lead, rubber, plastic or fibre 27 in a jig 25 and a modifying layer 28 of softer material than the steel is placed over the surface to be hardened. A sheet 29 of explosive material is placed over the layer 28 and a cover member 30 comprising a manganese casting 31 vertically movable in guides 32 rests on the explosive material. When the layer 29 is exploded the cover member 30 yields upwardly to prevent rupture of the article: A yieldable sheet 33 may be placed between the explosive layer and the cover to protect the latter. Either or both of the explosive layer and the modifying layer are varied in thickness to control the hardening in different areas. In another embodiment the wheel treads 37 and 38 of a manganese steel railway crossing casting 35 (Fig. 7) are hardened by exploding strips 47 of explosive material which extend down over the side faces 48 of the wheel treads. The treads are hardened in turn so that the corners at the intersection of the treads receive a double treatment, thus increasing the depth of hardness in the metal adjacent the corners.

A relay valve for delivering a pressure proportional to a control pressure, comprises a valve member 35, loaded by a spring 34 towards a seat 36, the valve controlling flow from an inlet 30 to a cavity 38 which is connected to an outlet 40. The valve is actuated by a piston 46 having a skirt 48 sealingly slidable in a channel 50 of a pressure ratio ring 53. The ring 53 is clamped by a cover 14 and the channel 50 is connected to atmosphere through a passage 56 and exhaust 57 in the piston 46. An exhaust valve 64 connected to the stem of valve 35 co-operates with a seat 62 to control the exhaust of fluid from the cavity 38. In operation, control fluid is supplied through port 42 and acts on the piston 46 over an area A minus D to move the piston downwards to close exhaust valve 64 and open valve 36 to allow flow from the inlet to the outlet. The pressure in cavity 38 then acts on the piston 46 over an area B minus C and when the force due to the delivery pressure and springs 34, 36 equals the control pressure both valves 35, 64 are closed. A reduction in the control pressure allows the piston to move upwards to open the exhaust valve. The pressure ratio between control and delivery pressure can be varied by replacement of the piston 46 and pressure ratio ring 53 by ones of different channel sizes and the valve may be supplied with a set of such parts to provide selected ratios such as 1:1, 1:2, 1:3 &c. The replacement is made by removal of cover 14.
